6.4.2
Using external pump
NOTICE
–
WATCH THE GAS FLOW
Gas must be drawn out of the output in pump operation.
Gas input must be nearly having ambient pressure (deviation recommended less than 20
mbar) in pump operation.
The pump must draw out the gas from the PID module. Thereby gas and particle contamination from pump
is prevented.

6.4.3
Using without pump
NOTICE
–
WATCH THE GAS FLOW
Constant flow from active gas source will need (depending from pollution of dust and water
filter) 20 mbar to max 100 mbar overpressure to realize 200 to 300 ml/min flow through
module.
